4.4 Configuring VLAN Mapping of Double VLAN Tags

This section describes how to configure mapping of double VLAN tags.

4.4.1 Establishing the Configuration Task

4.4.2 Replacing the Outer VLAN Tag
4.4.3 Replacing the Double VLAN Tags
4.4.4 Checking the Configuration
4.4.1 Establishing the Configuration Task
Applicable Environment
When two private networks in different VLANs communicate with each other through a public
network, the user packets may carry one or two VLAN tags when arriving on the public network.
You can configure VLAN mapping of double VLAN tags on the edge device of the public
network so that the VLANs of private networks and public network can be separated. This saves
VLAN resources of the public network. Compared with VLAN mapping of single VLAN tag,
this function is more flexible and used in a wider scope.
4-4
Run the display vlan vlan-id command to check whether the interface is added to the local
VLAN.
Run the display current-configuration [ | { begin | exclude | include } regular-
expression ] command to display information about the VLAN mapping of single VLAN
tag on the interface.
Run the preceding command, and you can obtain the following information:
The interface is added to the local VLAN.
–
The information about the VLAN mapping is correct.
